随着科学技术的发展和计算机技术的广泛应用,非线性方程组问题得到了数值研

随着科学技术的发展和计算机技术的广泛应用,非线性方程组问题得到了数值研究人员越来越多的关注。在生产实践,科学技术和生活学习等各个方面,非线性关系是普遍存在的关系,也是最优化研究领域重要的课题。为了使非线性关系更好地服务于社会,适用于科学研究,非线性方程组的解法一直以来都在被科学家不断的寻找,尝试和创新。近年来许多学者提出了许多解非线性方程组的数值方法,其中比较普遍的方法就是迭代法,包括Newton迭代法,Ostrowski迭代法等。本文本文主要研究非线性方程组的求解问题,对Newton法进行改进,并且希望得到更高阶的收敛性。前言部分主要介绍了求解非线性方程组的研究背景和意义,概述了国内外对非线性方程组的解法的研究现状。最后,介绍了本文将做的工作。第二章,首先介绍了导数与中值定理的知识,这对之后为求解方程得到更高收敛性,用微分中值定理来近似三阶张量有很大的帮助。然后,介绍了迭代法求解非线性方程组以及收敛性。第三章,用Newton法求解非线性方程组,并且提出类似Newton迭代法的方法,还考虑了基于chebyshev方法的两步法,利用雅可比矩阵的差分逼近二次项,避免了三阶张量的计算和存储。同时,保持了该方法下的局部二次收敛性。第四章,主要是提出三阶收敛性的算法,并对其收敛性给予了证明。第五章,进行数值实验.......

With the development of science and technology and the widespread application of computer technology, the problem of nonlinear equations has received more and more attention from numerical researchers. In various aspects of production practice, science and technology, and life learning, non-linear relationships are ubiquitous relationships, and are also important topics in the field of optimization research. In order to make the nonlinear relationship better serve the society and be suitable for scientific research, the solution of the nonlinear equation system has been constantly sought, tried and innovated by scientists. <br>In recent years, many scholars have proposed many numerical methods for solving nonlinear equations. Among them, the more common method is the iterative method, including Newton iterative method and Ostrowski iterative method. This paper mainly studies the problem of solving nonlinear equations, improves the Newton method, and hopes to obtain higher order convergence. <br>The preface mainly introduces the research background and significance of solving nonlinear equations, and summarizes the research status of nonlinear equations at home and abroad.
